I was in the same boat as you last year, This is what I did over the summer, and what I'm very pleased with after 420 miles this year. Mine bottomed way too easy, even after they replaced the first blown shock. Because of that, the tunnel buckled, and they replaced that too. Anyhow, I'm convinced the shock needs to be revalved and resprung. Pioneer did mine, and it has much better bottoming resistance, as well as a wider range of adjustment on the electric adjust. I also put on the heavier spring. I weigh about 215 plus gear and consider myself a pretty aggressive rider. The suspension is far better this year, but make sure you get the ride in sag set properlly to the manual, its critical for proper suspension performance. That said, I still managed to bottom the sled occasionally, but not nearly as bad as before. It seems like after a half hour of hard hammering, the suspension action deteriorated, and the shock seemed to fade a bit. I suspect a thicker, or better quality suspension fluid would be the answer here, ask your dealer or suspension tuner. I set my transfer rod between standard and minimum, as I like flat power on cornering too. I'll sacrifice a little holeshot. I also bought the updated tunnel braces that the 07 comes with, I think its important to have these, and would have saved me a tunnel if I had them last year. On the front, I think the shocks and spring rate are fine imo. Like most, mine darted in some conditions. I listened to alot of people and what they did for fixes from new skis, duallies, etc.. I ended up going with a 6 inch Bergstrom triple points with shims and ski savers. No darting thats for sure, and still carves good. I'm pretty happy this year with this setup.
